What our customers say

From mid-market to enterprise: companies across industries map their processes with Nuclos.

The rollout was agile: Novabit implemented defined outcomes and flexibly adapted where we deviated. We have ERP software that fits our processes, stays affordable, and has no license fees.
Jürgen Dehner Secretary General · ARCD
Customer satisfaction comes first for us. The simpler the processes, the better. With Nuclos we fully automated and transparently mapped our leasing contract management. That reduces sources of error and saves time. The rollout was a milestone toward paperless company bike leasing.
Victoria Mittelbach Head of Platform Development · BusinessBike
Thanks to the modular design we can map processes including all information optimally. Novabit implements new requirements quickly. Interfaces to project management and site administration plus automations reduce the load on our planners and increase scalability.

What Nuclos 5 does differently

Five points where Nuclos 5 differs structurally from classic ERP projects.

Classic ERP project
Nuclos 5

Low-code and AI

Low-code and AI:

Rigid modules for flexibility, separate chatbots for AI. Both expensive, disconnected, and fragile.

Low-code and AI:

Low-code models processes, AI and MCP accelerate development and automation. All on one platform.

Time to value

Time to value:

12 to 18 months before the first productive system. Scope unclear, budget running.

Time to value:

Productive operation in about 30 days. Scope agreed, fixed price, plannable go-live.

Project risk

Project risk:

Long projects with uncertain outcomes. Budget overruns and delayed go-lives are the norm.

Project risk:

48h prototype for scope and ROI clarity, then fixed-price delivery. Risk calculable before the full project.

Vendor lock-in

Vendor lock-in:

Per-user licensing, proprietary code. Every customization costs extra or is simply not possible.

Vendor lock-in:

Open source: source code is yours. No license per customization, no vendor dependency.

Data sovereignty

Data sovereignty:

Unclear where data lives. Compliance risks and dependency on hosting partners.

Data sovereignty:

Made and hosted in Germany. GDPR-compliant, cloud or on-premise, data in your hands.

Frequently asked questions

Clarity before you decide: answers to the questions procurement, IT, and leadership ask.

What makes Nuclos the ideal open source ERP for the mid-market?
Nuclos is low-code toolkit and AI platform in one: processes adapt to you, not the other way around. As a German open-source solution, Nuclos gives mid-market companies full sovereignty over source code and data, predictable costs without per-user licenses, and long-term investment security.
How is Nuclos different from standard ERPs like Odoo or SAP?
The biggest difference is freedom. With Nuclos there is no vendor lock-in and no rigid licensing models. Low-code and AI make individual extensions fast and planable, with full control over source code and data.
Can I run Nuclos both on-premise and in the cloud?
Yes. Nuclos Cloud for a fast, maintenance-free start or on-premise on your servers. For high audit-compliance requirements, local installation is a proven choice. Both models use the same open-source platform.
From idea to prototype in 48h: how does the risk-free entry work?
In a two-day workshop we model one sub-process as a clickable ERP prototype in Nuclos, not a full requirements definition. Fixed price 950 Euro plus VAT. Your team tests the result. When you commission Nuclos Enterprise, we credit the investment and continue the prototype; it is not discarded.
What costs arise with an open source ERP without license fees?
With Nuclos, classic per-user license fees disappear. You invest in implementation, optional hosting, and enterprise support. Entry offers: 48h prototype (950 Euro plus VAT), specification by scope, Nuclos Enterprise from 10,000 Euro plus VAT, and Nuclos MCP as a subscription. Transparent on the pricing page.

Individual ERP, on your own terms.

Nuclos Enterprise, productive in 30 days on agreed scope, or self-built with Nuclos MCP, all on Nuclos 5.
